What is frontage road?

A frontage road is a local road running parallel to a higher-speed, limited-access road, such as a highway or freeway. Frontage roads are typically located on one or both sides of the main road and provide access to properties and businesses along the main road.

Frontage roads are designed to reduce congestion on the main road by providing an alternative route for local traffic. They also improve access to businesses and properties by providing a direct route for customers and delivery vehicles.

Frontage roads may have lower speed limits than the main road and are typically designed to accommodate slower-moving local traffic. They often include intersections, driveways, and traffic signals to facilitate access to adjacent properties.

Frontage roads are a common feature of highway and freeway systems in many countries and are an important component of urban and suburban transportation networks. They can also provide emergency access routes in case of accidents or other incidents on the main road.
